Patients with bleeding extremities can elevate the affected extremities appropriately. The purpose of doing so is to increase the venous blood flow back to the heart, which can pump blood to the brain, liver, kidneys and other important organs through the contraction of the heart, so as to maintain sufficient blood circulation to the important organs and avoid the failure of the important organs to endanger the patient’s life. However, if the bleeding from the extremities is large, simply elevating the affected extremities will not completely stop the bleeding, so the patient should go to the hospital as soon as possible to perform thorough wound debridement and local suturing to stop the bleeding. The bleeding should be controlled as soon as possible, and the patient should be given crystal, colloid, red blood cells and plasma to maintain effective blood circulation in time to avoid serious complications such as hemorrhagic shock and death.
